Over-Expression of Immunosuppressive Molecules, PD-L1 and PD-L2, in Ulcerative Colitis Patients

PD-L1 expression and tumor-infiltrating lymphocytes

Upon analysis of 636 primary breast carcinoma patient samples, we have found that programmed cell death ligand 1 (PD-L1) mRNA expression is associated with tumor-infiltrating lymphocytes (TILs). Furthermore, PD-L1 expression and elevated TILs were associated with longer recurrence-free survival. Thus, our findings indicate that PD-L1 is prognostic in breast cancer and suggests a functional link...

Imaging PD-L1 Expression with ImmunoPET

High sensitivity imaging tools could provide a more holistic view of target antigen expression to improve the identification of patients who might benefit from cancer immunotherapy. We developed for immunoPET a novel recombinant human IgG1 (termed C4) that potently binds an extracellular epitope on human and mouse PD-L1 and radiolabeled the antibody with zirconium-89. Small animal PET/CT studie...

Cell-specific PD-L1 expression in DLBCL.

In this issue of Blood, a new study by Kiyasu et al used a double-staining technique to identify cell-specific programmed cell death ligand 1 (PD-L1) expression in 1253 diffuse large B-cell lymphoma (DLBCL) samples and analyzed the findings together with programmed death-1 (PD-1) expression in tumorinfiltrating lymphocytes (TILs) and clinical outcomes, providing new insights into the role of th...
